Abstract: An organic light emitting diode (OLED) display device for displaying a white color using a first color and a second color that are complementary to each other. The OLED display device includes a substrate, a lower electrode on the substrate in a first direction, a first organic layer on a first region of the lower electrode and having a first EML for displaying a first color, a second organic layer on a second region of the lower electrode and having a second EML for displaying a second color that is complementary to the first color, and an upper electrode disposed on the first and second organic layers in a second direction crossing the first direction, wherein the first organic layer has a different thickness from the second organic layer. In addition, a thin film transistor (TFT) may disposed between the substrate and the lower electrode.

Abstract: An organic light-emitting device includes a substrate; a first electrode disposed on the substrate; a hole transport layer disposed on the first electrode; an emitting layer disposed on the hole transport layer; and a second electrode disposed on the emitting layer, wherein an organic layer is interposed between the first electrode and the hole transport layer, the organic layer including at least one fluorine-containing compound selected from the group consisting of a fluorine-substituted phthalocyanine derivative, an aliphatic fluorocarbon compound represented by CxF(2x+2), CxF(2x?2), or CxF2x, where x is an integer of 1 to 500, an aromatic fluorocarbon compound represented by C6yF6y?2n, where y is an integer of 1 to 80, n is an integer of 0 to 80, and 6y?2n is a positive integer, and fluorinated fullerene. The organic light-emitting device can show high efficiency, a low driving voltage, high brightness, and a long lifetime.

Abstract: A backlight unit for a liquid crystal display device (LCD), and an LCD including the same are disclosed. One embodiment of the backlight unit includes an organic light emitting element in which the efficiency of light extraction is improved without decreasing productivity to achieve high brightness and a low consumption power. The backlight unit includes a substrate, an organic light emitting element formed on the substrate, and an encapsulating member attached to the substrate to enclose the organic light emitting element. The backlight unit further includes a scattering film on one of surfaces of the substrate, the organic light emitting element and the encapsulating member to prevent light emitting from the organic light emitting element from being totally reflected.
